WIRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 403,620, dated May 21, 1889.

Serial No. 295,266. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK STILEs, of Burnet, in the county of Burnet and State of Texas, have invented a new and useful Improvement in \Vire-Stretchers, of which the following is a specification.

My invention is in the nature of an improved wire-stretching device for building and repairing wire fences, telegraph-lines, &c.; and it consists in the peculiar construction and arrangement of parts which I will now proceed to describe with reference to the drawings, in which Figure 1 is a side view of the device with one of the frame-bars removed. Fig. 2 is a top or plan view.

A A are two side bars of strap-iron, which are fastened together by bolts B 13', around one of which, B, there is arranged a sleeve or anti-friction roller. Between these two side bars there is journaled in suitable bearings therein a cog-wheel, C, which is rigidly connected to its axial shaft, and this latter has attached to it outside of the bars A a crank-handle, D, by which the cog-wheel is turned.

F is a chain which passes over the cogwheel, and is drawn up thereby to tighten the wire. To connect this chain to the wire to be drawn up, a wire-holder or gripping device, G H, is employed. This consists of a plate, G, having slotted ears or lugs 19 and a hook, (I, which latter enters into one of the links of the chain. In the slot of the ears I) are seated the trunnions e of a serrated camlever, H, which, when turned down, grips the wire between its serrated cam and the plate G. As the chain is drawn up by the cogwhee1,the latter is held to its position, and the slackening of the wire is prevented by a pawl or detent, E, pivoted between the bars A, and having a tooth that engages with the teeth of the cog-wheel. On the other side of the cog-wheel there is a cross-plate, J, connecting the two bars A, and a serrated camlever, I, for gripping the other end of the wire to give a purchase or hold for the machine in winding up the chain. This serrated cam-lever has trunnions c, that are inserted in right-angular slots in the side bars, and when said lever is turned down its serrated cam grips the wire W between it and the cross-plate J.

A is a handle fastened to the frame-bars A, which handle is grasped to steady the device while it is being operated by the crankhandle D.

I am aware of the fact that it is not broadly new in a wire-stretcher to combine a toothed wheel in a frame with a crank-handle and a chain for drawing up the wire, and I therefore only claim in this connection the peculiar arrangement of the detent or pawl in relation to the toothed wheel and the chain.

Having thus described my invention, what I claim as new is 1. The combination, in a wire-stretcher, of the side bars, A A, having a toothed wheel, 0, journaled between them and provided with a crank, a set of cross bars or bolts connecting the two side bars, a pawl, E, hung upon one of the cross-bars and having its toothed end arranged to abut against the teeth of the wheel, and a chain, F, passing over the toothed wheel and underneath the pawl, substantially as shown and described.

2. The combination, with the frame-bars A, having right-angular slots to, of the grippingcam-lever I, having trunnions c, fitting in said slots, and the cross bar J, connecting the frame-bars and forming a bearing beneath the cam-lever to grip the wire against, as shown and described.

3. The combination of frame-barsA A,with connecting-bolts B B, cross-plate J, and slots 60, the gripping cam-lever I, cog-Wheel O, with attached crank, detent E, chain F, and wireholder G H, attached to the chain, substantially as shown and described.
